12 best flexible tyre couplings
Flexible tyre couplings are mechanical devices used to connect two shafts in order to transmit torque while accommodating misalignments and reducing vibration in industrial applications. These couplings fall under the category of power transmission components and are widely used in machinery where flexibility and shock absorption are crucial.Here are the key aspects of flexible tyre couplings:
**1. ** Design and Components: Flexible tyre couplings consist of two flanges, often made of high-quality cast iron, steel, or aluminum, which are connected by an elastomeric tyre made of rubber or polyurethane. The tyre is flexible and acts as a cushion between the flanges. The tyre has a star-shaped or spider-shaped cross-section, providing elasticity and torsional flexibility.
**2. ** Misalignment Compensation: One of the primary functions of flexible tyre couplings is to compensate for misalignments between the connected shafts. These misalignments can be angular, parallel, or axial. The elastomeric tyre can flex and deform slightly to accommodate these misalignments, ensuring smooth operation and reducing wear on connected machinery.
**3. ** Shock Absorption: Flexible tyre couplings are excellent at absorbing shocks and dampening vibrations. In industrial environments where machinery is subjected to sudden shocks or vibrations, these couplings help protect the connected equipment from damage, ensuring a longer lifespan and improved operational efficiency.
**4. ** Easy Installation and Maintenance: These couplings are relatively easy to install and require minimal maintenance. They do not need lubrication, which reduces maintenance efforts and costs. Periodic visual inspections are usually sufficient to ensure their proper functioning.
**5. ** Applications: Flexible tyre couplings find applications in various industries, including manufacturing, mining, automotive, and agriculture. They are commonly used in pumps, compressors, conveyors, and other rotating equipment where torque needs to be transmitted smoothly while accommodating misalignments and minimizing vibrations.
**6. ** Advantages:
- Easy to install and maintain.
- Dampen vibrations and absorb shocks, reducing wear on machinery.
- Accommodate misalignments, ensuring smooth operation and longer equipment life.
- Suitable for a wide range of industrial applications.
- Cost-effective solution for power transmission in machinery.
In summary, flexible tyre couplings are essential components in industrial machinery, providing flexibility, shock absorption, and misalignment compensation. They contribute significantly to the smooth and efficient operation of various industrial applications, ensuring the longevity of connected equipment.

User questions & answers
| Question: | can this be used with porter cable 135 compressor |
| Answer: | Yes this will fit. You just need the correct adapter available at any hardware store. |
| Question: | What is the lowest psi reading this can read (accurately |
| Answer: | Hello, dear Pawel, Rated pressure: 0-100psi Max pressure: 150psiThe information above is its pressure range. Technically, it will read every psi it detects, but considering the pressure is too low in some case, it will starting reading from 5 psi. Hope this will help. |
| Question: | Am I missing something? I've got air in the tank but when on the tire it wont pump air? Off the tire it works just fine |
| Answer: | If the hose line clamp is not fully engaged, it will NOT work. Try not using the clamp by pressing it open and fully placing the end onto the stem. Then pull the trigger to deliver the air. |
| Question: | Can I used this for reading the pressure and not being connected to an air compressor |
| Answer: | Yes it can. You just need to press to on/mode select bottom when connected to your tire. Result reading is pressure in connected tire. Hope this helps you. |

User questions & answers
| Question: | Is there a presta valve version of this |
| Answer: | Dear customer, I am sorry that we only have schrader valve stem version at present. Best regards! Lumiteco Customer Support |
| Question: | Why doesn’t it come with a standard air hose adaptor? Looks like you have to screw Oman adaptor to connect to your shop air line |
| Answer: | I bought this item to put on my portable air compressor that I carry in my car. My portable air compressor has a screw-on fitting on the end of the hose that connects to the Schrader valve on the wheel of the car. While I am screwing my air compressor onto the valve I lose some air and it takes anywhere from 15 to 30 seconds. So I purchased this device to permanently screw onto the end of the air compressor hose. The other end of the device is a lever-type quick connect that I can connect to the valve on the wheel in about 1 second. That way I don’t lose a psi or two when I disconnect the air hose from the wheel. |
| Question: | how big is the head of this? i need a low profile head |
| Answer: | I don't know what a low profile head is, but this works great on standard valve stems. |
